About the Role

We are looking for a Senior Blockchain Developer with hands-on experience across blockchain protocols and cross-chain solutions. Your first and most critical task will be the integration of the Ton blockchain into Chainlink CCIP, so experience—or the ability to quickly get up to speed—with Ton, Chainlink, and cross-chain technologies is essential. This is a high-impact role, ideal for someone who thrives in a fast-paced, deeply technical environment. We're seeking someone who can ramp up quickly and deliver immediate value.

Key Responsibilities

• Lead the integration of Ton blockchain into Chainlink CCIP.

• Develop, test, and deploy cross-chain bridging solutions.

• Collaborate with protocol and infrastructure teams to ensure seamless interoperability across chains.

• Write clean, secure, and maintainable code using TypeScript and Next.js.

• Stay up-to-date with emerging blockchain technologies like SUI and Canton, and contribute to architectural discussions.

Required Qualifications

• Must be located in the U.S. or Canada

• Senior-level experience (5+ years preferred) in blockchain development.

• Proven expertise with Chainlink, cross-chain bridges, and non-EVM blockchain networks.

• Strong understanding of decentralized systems and blockchain interoperability.

• Experience or demonstrated ability to quickly learn Ton blockchain.

• Proficiency in TypeScript and Next.js.

Nice to Have

• Experience with emerging protocols such as SUI and Canton.

• Familiarity with Chainlink CCIP architecture and its extensibility model.

• Prior work in DeFi, cross-chain DApps, or oracle integration.

Note:If you are not familiar with Ton but are a fast learner with strong fundamentals in blockchain and cross-chain technologies, we still encourage you to apply.
